lumbar puncture (LP) | insertion of a needles into subarachnoid space usu b/w 3rd and 4th lumbar vertebrae |
magnetic resonance imaging of the brain or spine (MRI) | noninvasive procedure; produces sectional images of soft tissues of brain and spine thru a strong magnetic field; uses no radiation; used to visualize tumors, edema, MS, and herniated disks |
positron emission tomography of the brain (PET scan) | imaging technique with radioactive substance that produces sectional imaging of the brain to examine blood flow and metabolic activity; images projected on a viewing screen |
Alzheimer disease (AD) | dz charac by early senility, confusion, loss of recognition of persons or familiar surroundings, restlessness, & impaired memory |

Bell palsy | paralysis of muscles on one side of the face, usu temporary |
cerebral aneurysm | aneurysm in the cerebrum |
cerebral embolism | embolus lodges in cerebral artery, causing sudden blockage of blood supply to brain tissue: type of ischemic stroke; common cause is atrial fibrillation |
cerebral palsy (CP) | condition of lack of muscle control and partial paralysis, caused by brain defect or lesion present at birth or shortly after |
dementia | cognitive impairment with a loss of intellectual brain function; not normal aging; several causes; difficulty in performing complex tasks, reasoning, learning and retaining new info, orientation, word finding, and behavior |
epilepsy | disorder; main symptom is recurring seizures |
hydrocephalus | increased amt of CSF in the brain ventricles; can cause craniomegaly in infants |
intracerebral hemorrhage | bleeding into the brain as a result of a ruptured blood vessel w/i the brain; symptoms vary w/ location and often develop suddenly: include dyspnea, dysphagia, aphasia, diminished LOC, hemiparesis; type of ischemic stroke; assoc w/ high BP |
multiple sclerosis (MS) | degenerative dz charac by sclerotic patches along the brain and spinal cord |

sciatica | inflammation of the sciatic nerve, causing pain that travels from the thigh thru the leg to the foot and toes; caused by injury, infection, arthritis, herniated disk, prolonged pressure on the nerve from long-term sitting |
shingles | viral dz caused by herpes zoster that affects peripheral nerves & causes blisters on the skin that follow the course of the affected nerves |

Funtion of the nervous and endocrine systems | regulating and controlling activities of the other body systems |
Brain | major portion of the CNS |
cerebrum | largest portion of the brain, divided into left and right hemispheres; controls the skeletal muscles, interprets general senses, contains centers for sight and hearing; site of intellect, memory, and emotional reactions |
ventricles | spaces w/i brain that contain CSF, which flows thru the subarachnoid space around the brain and SC |
cerebellum | located under posterior portion of the cerebrum; function: to assist in the coordination of skeletal muscles & to maintain balance; a.k.a. hindbrain |
brainstem | connects brain to the spinal cord; site where ten of the 12 cranial nerves originate |
pons | "bridge"; connects the cerebrum w/ the cerebellum and brainstem; part of brainstem |
medulla oblongata | located b/w pons and SC; contains centers that control respiration, heart rate, muscles in blood vessel walls (which assist in determining BP); part of brainstem |
midbrain | superior portion of brainstem |
cerebrospinal fluid (CSF) | clear, colorless fluid in ventricles that flows thru subarachnoid space in brain and SC; cushions brain and SC from shock, transports nutrients, clears metabolic waste |
spinal cord | passes thru the vertebral canal extending from the medulla oblongata to the level of 2nd lumbar vertebra; conducts nerve impulses to & from brain and initiates reflex action to sensory info w/o input from the brain |
meninges | 3 layers of membrane that cover brain and spinal cord |
dura mater | tough outer layer of the meninges |
arachnoid | delicate middle layer of meninges; loosely attached to pia mater by weblike fingers, allowing for subarachnoid space |
pia mater | thin inner layer of the meninges |
nerve | cordlike structure that carries impulses from one part of the body to another; 12 pairs of cranial; 31 pairs spinal |
ganglion | group of nerve cell bodies located outside CNS |
glia | cells that form support and nourish nervous tissue; some assist in CSF secretion and others assist w/ phagocytosis |
Types o Glia | astroglia, oligodengroglia, microglia |
neuron | conducts nerve impulses to carry out the function of the nervous system; cannot be replaced, if destroyed |
